国内火力发电厂煤粉锅炉的燃烧调整,绝大部分采用调整一、二次风静压的方法来实现,但是传统的静压测量方法,不能正常反映一、二次风道内的配风情况,这是由于各风道的长短、弯头的多少、风门的开度、煤粉的浓度等各不相同,虽然测得的静压相差不大,然而进入炉膛参加燃烧的一、二次风量却相差甚多.虽然部分厂家安装了一次风速测量装置,但是由于耐磨和防堵性能不好,运行过程中起不到准确监测作用.

Domestic coal-fired power plant pulverized coal boiler combustion adjustment, the adjustmentof the primary and secondary air static pressure method to realize, but the traditional static pressure measurement method, can’t normal reflect the primary and secondary air duct in the air distributionsituation, this is due to the length of the duct and the bend of how many, the throttle opening, and the influences of the concentration of each are not identical, although measured static differ not quite, butinto the furnace to the burning of the primary and secondary air is radically different. Although some factory installed a wind speed measuring device, but due to wear and containment performance is not good,in the operation process of the less than accurate monitoring function.
